烤烟品种云烟85的化学成分研究

Research on Chemical Constituents from Flue-cured Tobacco Yunyan 85

利用色谱技术和制备高效液相色谱法对云烟85进行植化研究,分离得到9个化合物.经MS和NMR等波谱方法及其理化性质分析,分别鉴定为:2-(4-烯丙基-2,6-二甲氧基-苯氧基)-1-(3,4,-二甲氧基,5-羟基-苯基)-丙-1-醇(1),2-(4-烯丙基-2,6-二甲氧基-苯氧基)-1-(3,4,5-三甲氧基-苯基)-丙-1-醇(2),玫瑰B类黄酮(3),异黄酮(4),塔巴联苯D(5),咖啡酸(6),6-羟基-7,3’,4’,5’-四甲氧基异黄酮(7),7-羟基-3-(4-羟基-苯基)-苯并吡喃-4-酮(8),5,7-二羟基-3-(4-羟基-苯基)-苯并吡喃-4酮(9).在确定结构的9个化合物中,(1),(2),(4)为首次从烟草中分离得到.

The phytochemical study was made with Flue-cured Tobacco Yunyan 85 by chromatographic technique and preparative high performance liquid chromatography to isolate nine compounds, and then to analyze their physical and chemical properties by spectroscopy analysis(MS,NMR). They were identified as(1) Fargesiphenol A,(2) Rhaphidecursinol A,(3) Rugosaflavonoids B,(4) Licoisoflavone,(5) Tababiphenyl D,(6) Caffeic acid,(7) Scopoletin(6-hydroxy-7,3’,4’,5’-tetramethoxy-isoflavone),(8)7-Hydroxy-3-(4-hydrxy-ohengy)-chromen-4-one,(9) 5,7-Dihydroxy-3-(4-hydrxy-ohengy)-chromen-4-one. Among the nine compounds with determined structure,(1),(2) and(4) were isolated from tobacco for the first time.
